Leave it up to Houstonians to stand up and join the cause. Not even 48 hours after Walters announced that longtime owner/den mother Pam Robinson was battling Stage 4 cancer, that single status update had already reached 15,000 people through shares, likes and comments. Plans for this three-day benefit for her were announced almost immediately.

Currently, 20 bands have stepped forward to contribute their time and talents to the cause, which Walters is labeling"Keep Calm//Fight Cancer." Tonight, many of Houston's top indie acts come together, from the Tontons and New York City Queens to Second Lovers and Featherface. Saturday is reserved for hardcore and punk bands such as Pride Kills, Black Congress and Peloton, before Sunday's show welcomes acts like The Last Starfighter, Pbearadactyl (sic) and Safe Haven.

But it wouldn't be a benefit without eats from some of Houston's delicious food trucks, as well as a silent auction, where benefit-goers can bid on things like Fun Fun Fun Fest passes, local artwork, salon gift certificates and more. Each show will cost $10 for entry, and 100 percent of the proceeds from both tickets and the silent auction will go towards paying for Robinson's medical needs. ALYSSA DUPREE

KrewellaStereo Live, September 6

Krewella was afforded one of the highest honors a contemporary act can receive back in May, when their air-punching neon jam "Alive" landed on the 46th iteration of earworm almanac Now That's What I Call Music. (Their neighbors included Justin Timberlake, Taylor Swift and Ke$ha.)

The Chicago-based singing sisters Jahan and Yasmine Yousaf -- who you may be impressed to learn were born in Houston -- and trusty producer Rain Man have become a go-to act at EDM festivals including Ultra, Electric Daisy Carnival and Spring Awakening behind other supersize-fun songs like "Play Hard," and "Can't Control Myself." Now debut full-length Get Wet is sandwiched into Columbia Records' fall release schedule between John Legend and MGMT, further proof that Krewella belongs in the big leagues. With Seven Lions and Candyland. CHRIS GRAY

Chelsea WolfeFitzgerald's, September 7

Severe, ominous and spectral aptly describe Chelsea Wolfe, whose electronica-flecked new album Pain Is Beauty (Sargent House) has a foreboding sound that matches its Bronte-esque cover art. The five-piece L.A. band, named after its possibly pseudonymous lead singer (catch the clever Jack London pun?), debuted with 2010's The Grime and the Glow before softening its more metallic elements last year on the more folk-sounding Unknown Rooms.

Fans of both pain and beauty -- to say nothing of P.J. Harvey and Tori Amos -- will find plenty to appreciate here, with songs like "Feral Love," "The Warden," "Sick," and most of all on pensive eight-minute epic "The Waves Have Come." With True Widow. CHRIS GRAY

Dr. JohnMiller Outdoor Theatre, September 7

Easily one of New Orleans' most beloved and recognizable musicians, Dr. John has been coming to Houston for a long time; the "Night Tripper" even preceded Isaac Hayes, Stevie Wonder and Bob Dylan's Rolling Thunder Revue at the famous January 1976 "Night of the Hurricane" Astrodome concert. By then the man born Mac Rebennack and schooled by R&B masters Professor Longhair and Earl King was more than a decade into his career and coming off a big rock hit with 1974's "Right Place, Wrong Time."

The Night Tripper comes to Saturday's free Miller Outdoor show at yet another career peak thanks to recent albums City That Care Forgot (a Katrina lament), Tribal and last year's Locked Down, where the Black Keys' Dan Auerbach helped the Doctor polish up that familiar gris-gris. He'll put a spell on you. CHRIS GRAY

Cafe TacubaArena Theatre, September 8

Credited for the rise of Spanish rock during the '90s, Cafe Tacuba -- or Tacvba, as it's sometimes spelled -- hardly just incorporates Spanish lyrics into traditional rock. Instead Tacvba pulls from the melting pot of influences that surrounded them in their native Mexico City, while incorporating elements of alt-rockers like The Cure and The Clash. What was -- and is -- unique about the band, especially during their early days, is their skill at encompassing the artistic influences around them; their name is even borrowed from a coffee shop on Tacuba Street in Mexico City.
